Let's divide 263665 by 51
We want to figure out the number of times 263665 can be divided by 51.

Let's proceed to step 1:
If we divide 2 by 51, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 51

On to step 2:
26 divided by 51 is 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 51

Let's proceed to step 3:
The number 51 fits into 263 5 times, leaving a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 255 away from 263, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 51

Let's proceed to step 4:
51 goes into 86 1 times with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 35 after subtracting 51 from 86.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 51

Let's proceed to step 5:
If we divide 356 by 51, we get 6 and a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 516.0
If we subtract 306 from 356, we get 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 51

Going ahead to step 6:
The number 51 fits into 505 9 times, leaving a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 5169.0
If we take 459 away from 505, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
If we divide 460 by 51, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 5169.9
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
10 divided by 51 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5169.9
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 51, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 5169.901
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 10:
If we divide 490 by 51, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 5169.9019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
When dividing 310 by 51, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 5169.90196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
If we divide 40 by 51, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5169.90196
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 5169.9019607
If we take 357 away from 400, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 14:
If we divide 430 by 51, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 5169.90196078
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 5169.90196078 and a remainder of 2.2e-08.
